The pressure gauge passes through the elastic deformation of the sensitive elements (Bourdon tube, bellows, bellows) in the watch, and then the pressure deformation is transmitted to the pointer by the conversion mechanism of the movement in the watch, causing the pointer to rotate to display the pressure.
The main structure of the pressure gauge.Pressure gauge dials Suppliers
Overflow hole: When the Bourdon tube bursts,
The internal pressure will be released through the overflow hole to prevent the glass panel from bursting. Note: In order to maintain the normal performance of the overflow hole, at least 10mm of space must be left behind the surface, and the overflow hole cannot be modified or blocked.
Pointer: In addition to standard pointers, other pointers are also optional.
Glass plate: In addition to standard glass, glass of other special materials, such as tempered glass, non-reflective glass, also shot glass.
Performance classification: normal (standard), steam normal (M), heat resistance (H), vibration resistance (V), steam vibration resistance (MV), heat resistance and vibration resistance (HV).
Treatment method: During the manufacturing process, oil-free/water-free treatment is used to remove the water or oil remaining in the water-receiving part.
Throttle valve (optional): In order to reduce the pulsating pressure, the throttle valve is installed at the pressure inlet.
The pressure gauge is divided into vacuum gauge, pressure vacuum gauge, micro pressure gauge, low pressure gauge, medium pressure gauge and high pressure gauge according to its measuring range. The vacuum gauge is used to measure the pressure value less than atmospheric pressure; the pressure vacuum gauge is used to measure the pressure value less than the atmospheric pressure; the micro pressure gauge is used to measure the pressure value less than 6; the low pressure gauge is used to measure the pressure value of 0-6 MPa; The medium pressure gauge is used to measure the pressure value of 10~60 MPa;
According to the purpose of the pressure gauge, it can be divided into ordinary pressure gauge, ammonia pressure gauge, oxygen pressure gauge, electric contact pressure gauge, remote transmission pressure gauge, vibration resistant pressure gauge, pressure gauge with inspection pointer, double needle double tube or double needle single Tube pressure gauge, digital pressure gauge.
